Batteries for grid storage have different properties than batteries for cars.
- Weight doesn't matter for grid storage.
- Recharge time need not be faster than discharge rate.
- Grid storage batteries should last a decade or two. Car storage batteries only need a working life of a few thousand hours.
- Efficiency over a charge/discharge cycle matters more for grid storage.
So grid storage tends to use different battery technologies than vehicles.
